She's so cute!! She looks yorkie to me. If she's not 100% a breed that looks awefully similar is a silky terrier. Mine is 75% silky 25% yorkie. Silky terriers are a tad larger, longer, and have a longer snout. My Isla looked exactly like a yorkie as a baby (12 weeks) but now that she's 4 1/2 months old you can tell her snout has elongated like the silky in her. Her color has never been "correct" for either a yorkie or silky but I still love her. She may have more of a yorkie size, though, cause at 4 1/2 months she's only 4 pounds yet. Who knows? There are big yorkies and small silkies. Yours, however, looks very adorable yorkieish!!!
